Product Description

**Key Selling Points**
 

195mm/320mm Precision Design | Lead-Free Tempered Glass | IEC 60383 & ANSI Certified

55kN Ultimate Tensile Strength
 

**Product Overview**

Product Description

Engineered for cross-border HVDC(High Voltage Direct Current) projects and grid modernization, the U300B suspension glass insulator delivers unparalleled performance in extreme environments (coastal salt fog, desert sandstorms, and -40°C Arctic conditions). Its 7-shed anti-pollution profile increases flashover voltage by 35% compared to conventional designs, slashing maintenance costs for utilities and EPC (Engineering, Procurement, and Construction) contractors.
